The AIDS virus has an external envelope, made of lipid and protein. This envelope is derived from the cell membrane of the host cell in which the virus replicated. The virus contains reverse transcriptase enzyme. AIDS stands for Acquired Immune Deficiency Syndrome; meaning that one is able to catch it, it is a weakness in the body’s system that fights diseases, and is a group of health problems that makes up a disease. A virus called HIV (Human Immunodeficiency Virus) causes AIDS.
From the common cold to cancers, viruses plague humans with disease and misery. Some of them, such as influenza, adapt and evolve as quickly as defenses are built against them. Some get into cells and start replication immediately. Others lie dormant like opportunistic predators until conditions are ripe for them to propagate. The herpes viruses can do this over and over again.
Viruses, bacteria, and prions can be rather similar. For example, their ability to affect a cell’s reproduction cycle, or their negative results for the structures they affect. On the other hand, bacteria can actually be beneficial to the structures they infect. Another difference is that bacteria reproduce without assistance. These three infectious devils are extremely unique but vaguely familiar at the same time.
5.) The size and overall shape of the virus. 6.) The effects of the viruses.4 Viruses can directly cause damage to the cells by seizing the cells metabolic resources and/or by producing toxic components which interfere with their normal functions. These viruses will generally make what is known as a cytopathic effect (CPE) in tissue culture cells.

During these steps the virus is extremely vulnerable and can be disrupted by pharmaceuticals. The first stage of the virus undergoes is binding. Binding is when the virus attaches to the cell and allows the virus do what is called fusion . This is when the virus and the cell membrane fuse, allowing the virus into the cell. Once the virus is in the cell, it then uncoats itself freeing viral genes and enzymes.
